Well first off it is not hard to Soft/Cap without purples and PvP. Second looking at your build you do not need the extra KB in fly, you already have 10 which is plenty. You also concentrated on some of the powers that you really do not need that high. Most content is either s/l/en/neg, hardly any fire or cold. You should of taken tuff/weave lot sooner then you did. Some of your attacks are under slotted for acc. I would of either 3 slotted or 4 slotted build up with 1 or 2 RR, and the rest in recharge. Maneuvers is under slotted for end it is a big end hog. I would also switch your kick to boxing for kick KBs opponents. Of course that is me who hates being a melee and having a foe I am fighting getting KBed and out of my reach. I probably missed some stuff and some one will pick it up.
I agree with LSK suggestions, and in addition you seem to be slotting sets that give primarily positional defense rather than typed--Gaussian's, BotZ etc.
I also think that Assault is a wasted pick, you'd be better off getting Incinerate instead. It's a good attack, and it'll give you another place to put a Kin Combat set.
From the top:
HPT needs more Heal slotting to maximize the HP boost. Move the Steadfast +Def to another power, SoW would be a good choice.
Fire Sword and Scorch each need another slot so they're slotted adequately for accuracy and damage. I like the Mako's quad as a fifth slot, but any IO with accuracy and damage will do.
Why take Air Sup if you're not going to slot it? If you really want it slot it with another set of Kin Combat and a fifth slot, otherwise just take Hover instead.
Drop the Aegis set in MoB and slot Reactive Armor there instead. Another option if you can soft-cap S/L without the RA set in HPT is to put the Aegis set there, but skip the Psi/Status IO.
Resistance slotting in IW only increases Psi resists--not a high priority. If you need slots elsewhere that would be a good place to take them from.
The BotZ defense bonus are pitiful for typed defense. Pull everything but the base slot and slot a Winter's Gift instead. WP does not need additional KB protection.
Oblit is not a great set for typed defense builds because the defense bonus is pretty small for six slots and it's low in end reduction, but I really don't see the point in 5 slotting an attack with it when you're not soft-capped to S/L. If you can soft-cap without it, consider using Eradication or Scirocco's Dervish instead.
The Red Fortune bonuses aren't that great. If you don't want to use another LotG set, consider Gift of the Ancients instead.
Quick Recovery is underslotted for end mod. If you can't afford another slot, consider replacing the End Mod/Rchg with an End Mod common.
Heightened Senses has a higher defense value than CJ, so you should be slotting it more heavily. Also, be sure to use both the Def/End and Def/End/Rchg so it has sufficient end reduction.
Maneuvers is a high-end toggle with a low base defense value--lower than CJ. If you can't afford to give it another slot go with Def/End, Def, and Def/End/Rchg and move the +Recharge elsewhere.
As LSK suggested, try a Rectified Reticle set in Build Up instead of the Gaussian's. You'll get slightly more S/L defense and it'll save a lot of slots.
SoW doesn't need to be slotted so heavily to hard cap S/L resistance. I'd put the Steadfast +Def in the base slot and leave it at that.
Greater Fire Sword needs another slot; again, a Kin Combat set would do more for you there.
Here's my rework of your build, it's now soft-capped to S/L/E/NE and 41% F/C defense. I ended up keeping Assault and dropping Air Sup for Incinerate, but you can switch that if you wish. (Keep in mind it'll be hard finding slots for Air Sup if you keep Incinerate.) I'd really prefer to have Hasten, but you don't have any power pools free.

My Characters
Knight Court--A CoH Story Complete 2/3/2012
Wow, I see I have a lot to learn about making builds....
Thanks for the input, and the restructure of my build. 
Just a couple responses, I don't use Air Superiority as an attack per se, I use it as my "flapjack" move, keep bosses off their feet, bring down fliers, etc. That was why it had only an accuracy in it, make sure it hits. But with the restructured build I can simply put it back in instead of Incinerate. I only took Hover for a slot for a LotG Global recharge.
Boxing/Kick, either one I don't use, it is simply something I have to take to get to Tough, and Weave.
I took Assualt simply so I/we could do more damage. In my rough draft of the build, it was my last choice, and I juggled things around in this build so it just came up a little sooner.
Everything was slotted mostly for set bonuses. My choices were based on trying to make a well-rounded char, but apparently I don't quite have the knack for making an awesome build yet. I'll keep working on it. 
Thanks again!
-Tig
Been playing the game for over 2.5 years, and been mostly going along with what looks fun as far as builds, powers, etc. on my characters. However, with the increase in end game content, increased level of mobs involved, I've noticed my survivability has taken a drastic plunge. So that being said, I've sat down with Mids, and really gotten into it, and have came up with this build that will hopefully give me survivability, usefullness, and fun while I play. Any and all feedback is defintely welcome.
Some things to note, my preferred travel power is Fly. The others I have trouble with controlling my char... >.>
Not sure if it's Mids, or something on my comp, but the toggles, Accolades, and Incarnate don't always stay on when I load or save a build, make sure they are on.
I'd prefer to keep this build Purple/PvP set free. I don't intend on sinking the kind of money into this build that those sets would require.
